I also have had no luck with my frozen pollen (that I know of, - I haven't kept track formally but it seems to me no pods developed from frozen-pollen crosses) but by next year I hope to try tracking pollinated flowers with a designation for whether the pollen was fresh or frozen. It would be so much easier to make hoped-for crosses with frozen since the desired partners are so seldom open at the same time. I do wonder if taking out previously frozen batches of pollen (to add newly-dried pollen in) thaws the old and makes it all non-viable...?
Here's a question for those who store pollen from doubles. Often, the pollen on a double is incorporated directly into a petal, and even using tweezers to remove it from the flower will bring a bit of petal with it. Since it is bad to have a moist part of the stamen (or, I assume, petal) in with the pollen, how to you remove pieces of attached petals? I find it very hard to separate the pollen capsule from the bit of petal, and I can see the petal is quite moist and sticky.
I'd love to see Juli's in-progress video when ready - hope you will post here with a link when it is done!
